The AMG 6.3-litre V8 engine in the new E 63 AMG develops an output of 386 kW/525 hp and a torque of 630 newton metres, matching the outstanding figures for the SL 63 AMG. The high-performance roadster has also donated its AMG SPEEDSHIFT MCT 7-speed sports transmission to the new model. This transmission dispenses with a conventional torque converter and uses a compact, wet start-up clutch. In conjunction with the four individual driving modes, the double-declutching and RACESTART functions, the resulting direct connection to the powertrain allows an extremely emotional and highly dynamic driving experience. The drive unit is unique in this segment, and ensures decidedly sporty performance figures: the E 63 AMG accelerates from standstill to 100 km/h in just 4.5 seconds, with a top speed of 250 km/h (electronically limited). The fast-revving, naturally aspirated engine with a displacement of 6208 cc impresses with its agile responsiveness, muscular power delivery and great flexibility. The newly composed AMG V8 sound is a thrilling accompaniment for mile after mile, while the smooth-running engine guarantees typical Mercedes long-distance comfort. A newly designed water cooling system ensures maximum endurance even under the enormous dynamic stresses of the racetrack.
